Question

I need to pass information between a form created from another form whats the best way to do this????

The forms need references to each other to pass information. If you're using .NET 2.0 the easiest way to get those references is to use the Application.OpenForms property which returns a FormCollection of every open form in the application. If you have two forms Form1 (the main form) and Form2 then this code will get the references you need: Form1 form1 = (Form1)Application.OpenForms[0]; Form2 form2 = (Form2)Application.OpenForms[1]; So if Form1 has a public TextBox (TextBox1 say) and you want to set the Text property from Form2 you can do: form1.TextBox1.Text = some text;
